Marc-Andre Carle had a great tweet about INFORMS 2012 conference : # orms is definitely the science of better: each software presented at # INFORMS2012 is better than its competitors This triggered two interesting blog entries by Nathan Brixius and Marc-Andre Carle on what it means to be better for a mathematical optimization solver. Not surprisingly the discussion focuses rapidly on better= faster , given speed is the easiest to measure among the dimensions Nathan outlined. I agree with most of what Nathan and Marc-Andre wrote and I... [More]

We also just announced a new release of our IBM ILOG ODM Enterprise product. This product complements CPLEX by providing a platform for advanced analytics solutions based on
optimization, with out-of-the-box features such as 'what-if' analysis,
user-friendly GUIs, and a repeatable implementation process for
deploying enterprise-wide, decision support. It includes features like a business data model, business user interfaces, client server architecture, data server, support for what-if analysis at the business level, etc. These... [More]

Update on June 28 2015. A more recent release of CPLEX is now available, namely CPLEX 12.6.2 . We just announced a new release of IBM CPLEX Optimization Studio. Interested readers can read the full announcement letter . Planned dates for availability are: November 16, 2012: Electronic availability November 23, 2012: Media availability Highlights for this release include enhancements that help improve Integrated Development Environment (IDE) modeling productivity and optimizer performance.

Optimization and Simulation are two different techniques that can be used to optimize a given system (system is used in a very broad sense here). In Optimization And Simulation Are Not The same I provided an example where optimization was the tool of choice when people might think that simulation was the tool of choice. As a conclusion of that post I discussed when optimization was best, and when simulation was best. What I didn't discuss though was when both should be used together. Here is such case. Simply put, simulation is required... [More]
